springMVC自定义错误处理主要是实现HandlerExceptionResolver这个接口来实现，里面方法public ModelAndView resolveException（）；

那么想做一个统一错误处理页面，直接在这个方法写上就可以了，实现例子如下：

package com.cwh.springmvc.Exception;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.springframework.web.servlet.HandlerExceptionResolver;import org.springframework.web.servlet.ModelAndView;public class CommonExceptionResolver implements HandlerExceptionResolver {private static final Log log = LogFactory.getLog(CommonExceptionResolver.class);@Overridepublic ModelAndView resolveException(HttpServletRequest arg0,HttpServletResponse arg1, Object arg2, Exception arg3) {log.info(arg3);arg3.printStackTrace();ModelAndView modelAndView = new ModelAndView();modelAndView.addObject("message",arg3.getMessage());modelAndView.setViewName("error");return modelAndView;}}

我做的统一处理页面为error.jsp这个页面，页面简单打印一下错误message:

<body>    This is a error page. <br>${message }  </body>

然后再springmvc的配置文件上加上这个异常处理的ybean:

<!-- 全局异常处理类 -->  <bean class="com.cwh.springmvc.Exception.CommonExceptionResolver"/>

接下来在代码中随便抛个错误：

 if(1 ==1)throw new Exception("this is a commonExceptionResolver");

运行结果如下：
